Question

我有一個要求，其中我想檢測兩種Android中

1. 每當呼出由與呼叫無關的事件，我的應用程序應該知道這與被叫號碼
2. 當電話掛了（由於成功/失敗）一起，我的應用程序應該知道這與掛斷

的原因沿着這是可能的Android中？

Answer 1

你應該創建一個BroadcastReceiver：

public class CallReciever extends BroadcastReceiver { 

    @Override 
    public void onReceive(Context context, Intent intent) { 

     if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(
       TelephonyManager.EXTRA_STATE_RINGING)) { 

       // Phone number 
       String incomingNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER); 

       // Ringing state 
       // This code will execute when the phone has an incoming call 
     } else if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(
       TelephonyManager.EXTRA_STATE_IDLE) 
       || intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(
         TelephonyManager.EXTRA_STATE_OFFHOOK)) { 

      // This code will execute when the call is answered or disconnected 
     } 

    } 
} 

你應該註冊你一個pplication聽清單中的這些意圖：

<receiver android:name=".CallReciever" > 
      <intent-filter> 
       <action android:name="android.intent.action.PHONE_STATE" /> 
      </intent-filter> 
</receiver> 

Answer 2

你需要創建一個接收器用於以下目的的行動：

1. 撥出號碼 - ACTION_NEW_OUTGOING_CALL
2. 電話掛斷 - ACTION_PHONE_STATE_CHANGED

有隻使用TelephonyManager和 PhoneStateListener.You鴕鳥政策甚至要註冊一個BroadcastReceiver一個簡單的解決方案。

public class MyPhoneStateListener extends PhoneStateListener { 

    @Override 
    public void onCallStateChanged(int state, String incomingNumber) { 
     switch (state) { 
      //Hangup 
      case TelephonyManager.CALL_STATE_IDLE: 
       break; 
      //Outgoing 
      case TelephonyManager.CALL_STATE_OFFHOOK: 
       break; 
      //Incoming 
      case TelephonyManager.CALL_STATE_RINGING: 
       break; 
     } 
    } 
} 

並註冊它：

public static void registerListener(Context context) { 
    ((TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE)).listen(new MyPhoneStateListener(), 
      PhoneStateListener.LISTEN_CALL_STATE); 
}
